OK, the demo as I posted works perfectly with iOS. Tested with my iPad. As soon as I am connected to my AP, my ON/OFF page is loaded.
On Android it fails. I checked my wifi Settings as set by the AP on android.
MAC: AC:22:0B:43:XX:XX (ommitting last 4)
SSID: esp8266
Hidden: NO
Link Speed: 54Mbps
RSSI: -42dBm
IP: 192.168.1.3
Netmask: 0.0.0.0 (for some reason this is not 255.255.255.0 as set by code)
Gateway: 192.168.1.1
DNS1: 192.168.1.1
DNS2: 0.0.0.0
DHCP Server: 192.168.1.1
DHCP Lease: 86400s
So it looks like the DNS server does not work correctly for Android 5.1.1
Tested also with an older version of Android (4.1.2), same result...does not work.
Can any one else please test on Android?
Posting my sketch as it currently is. tested using latest IDE and git sources for ESP. As said, works perfectly for iOS, but not for Android...direct access via IP works from all OS
